IMPROVBD CARPET-CLEANER.

TO ALL WHOM I'I MAY CONCERN:

Be it known that I, 'IHEoDoR LKE, of the city and county of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Carpet-Cleaning Machines; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made part of this specification, and in which- Figure I is a front view of a carpet-cleaning machine illustrating my invention.

Figure 2 is a rear viewot` the same.

Figure 3 is a vertical central section of the machine.

Figure 4 is an end elevation.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a machine, in which the carpet to be cleaned first has the dust beaten out by a number of swiftly-revolving lashes, and then, as it is drawn forward, the carpet has the dust brushed off by a rotary brush, as will be hereinafter more particularly described. l

The invention consists in the combination with the lashes, brush, and a rolling or windingmp windlass, of an open elastic frame, which serves to support that portion of the carpet under the immediate action of the lashes, the'better to adapt them to beat out the dust.

4 In order that others skilled in thc art to which my invention appertains may be enabled to fully understand and use the same, I will proceed to describe it in detail in connection with the accompanying drawings.

g represents a suitable frame, in which are mounted the horizontal shafts a, c, and le. The shafts a e are driven bypulleys and belts or otherwise, either by hand, horse, or steam-power. 7L L h area series of arms projecting radially from the shaft a, to which they are attached. The outer cntremities of the arms are to be provided with lashes of leather, rope, or other sufficiently tough material. The shaftl c has its periphery furnished with bristles, so as to forma rotary brush, as represented in gs. 2 and 3; and said shaft c is located at a proper distance below the shaft a to avoid interference with the revolution of the arms h. The'shaft 7c occupies the-lowest position of the three, and serves the purpose of a windlass upon which the carpet is wound or rolled up as it passes from the action of the lashes and brush. o is a shaft, placed in front of and at a point about equidistant from the shafts a and c. b Z represent a series of inclined rods or wires, attached'to a bar, z', and extending from the latter toward and nearly as far as thc shaft o. The frame composed of the rods b b may be braced at the back by a bar, yet itvmay have elasticity suicient to ,yield under the agellating action of the lashes attached to arms h h. The carpet is fastened to the shaft 7c, and rolled upon the latter whendusted by means of the hand-wheelf. From `the shaft lc the carpet is stretched over the roller o, and it hangs down against the front of the frame bb. I I

When thc machine is in operation, the lashes heat the dust from the carpet stretched upon the frame b b, which sustains the portion of the carpet under the action of the lashes, and thus the lashes are made to act effcctually and uniformly on all parts of the carpet. When the dust "is beaten out of thc part of carpet upon vframe b b, the carpet is slowly rolled up on windlass 7c, being, in the mean time, subjected to the action of the rotary brush c, which continues to brush of the dust' till another part of the carpet is adjusted on frame Z) b ready for the beating process. Thus the greater portion of the dust is expeditiously beaten from the carpet,

and that which adheres to the surface is removed by the brush c.

I-Iaving thus described my invention, what I claim as new herein, anddesire to secure by Letters Patent,'is The combination of the frame b Zw, shaft a, revolving arms t, rotary brush e, and windlass k, as herein described and for the purpose specicd. u
